WARNING
Adaptive Brake Assist cannot alwaysc learly
identify objects and comple xtraffic
situations. In these cases, Adaptive Brake
Assist may not intervene. There is arisk of an
accident.
Always pay carefu lattention to the traffic
situation and be read ytobrake. G
WARNING
Adaptive Brake Assist does not react:
R to people or animals
R to oncoming vehicles
R to crossing traffic
R to stationary obstacles
R when cornering
As aresult, Adaptive Brake Assist may not
intervene in all critical conditions. There is a
risk of an accident.
Always pay carefu lattention to the traffic
situation and be read ytobrake.
Due to the nature of the system, particularly
complicated but non-critical driving
conditions may alsoc auseBrake Assist to
intervene.
Adaptive Brake Assist aidsy ou in braking
during hazardous situations at speeds above
4m ph (7 km/h) and uses the radar sensor
system to evaluate the traffic situation.
With the help of asenso rsystem, adaptive
Brake Assis tcan detect obstacle sthata re in
th ep athofy our vehicle for an extended
period of time.
Should you approach an obstacle and
Adaptive Brake Assist has detected ariskof
collision, Adaptiv eBrake Assist calculate sthe
braking force necessary to avoid arear-end
collision. Should yo uapply the brakes
vigorously ,Adaptiv eBrake Assist will
automaticall yincreas ethe braking force to a
level suitabl efor the traffic conditions.
X Kee pthe brake pedal depressed unti lthe
emergency braking situation is over.
ABS prevents the wheel sfrom locking. The brakes will work normall
yagain if:
R yo ur elease the brake pedal
R there is no longe rany dange rofarear-end
collision.
R no obstacl eisdetected in front of your
vehicle
Adaptive Brake Assist is then deactivated.
Up to vehicl espeeds of around 155 mph
(250 km/h) ,adaptive Brake Assist is capable
of reacting to moving objects that have
already been recognized as such at least once
over the period of observation. Adaptive
Brake Assist does not react to stationary
obstacles.
If Adaptive Brake Assist is not available due
to am alfunction in the rada rsensor system,
the brake system remains available with full
brake boosting effect and BAS.
In particular, the detection of obstacles can
be impaired if there is:
R dirt on the sensors or anything else
covering the sensors
R snow or heavy rain
R interference by other rada rsources
R there are strongr adar reflections, for
example in parking garages
R an arrow vehicle traveling in front,e .g. a
motorbike
R av ehicle traveling in front on adifferent line
relative to the center of your vehicle
Following damage to the front end of the
vehicle, have the configuration and operation
of the radar sensor checked at aqualified
specialist workshop. This also applies to
collisions at low speeds where there is no
visible damage to the front of the vehicle.
COLLISION PREVENTION ASSIST PLUS General information
COLLISION PREVENTION ASSIST PLUS is
only available on vehicles with DISTRONIC.

If the driver's seat belt is fastened,
COLLISION PREVENTION ASSIST PLUS can
brake automaticallyw ithinaspeed range of
between 4mph (7 km/h) and 124 mph
(200 km/h).
COLLISION PREVENTION ASSIS TPLUS can
also react to stationary obstacle swith
automatic braking within aspeed range of
betwee n4mph (7 km/h) and 19 mph
(30 km/h).
In particular, the detection of obstacle scan

visible damage to the front of the vehicle. Adaptive brake lights
Adaptive Brake Assist warns following traffic
in an emergenc ybraking situation:
R by means of flashing brake lamps
R by activatin gthe hazard warning lamps
If you brake sharply from aspeed of more
than 70 km/ht oastandstill, the hazard
warning lamps are activated automatically. If
the brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h. You can also switchoff
the hazar dwarnin glamps using the hazard
warnin gbutton (Y page 107). ESP

(Electronic Stability Program)
General notes i
Observe the "Importan tsafet ynotes"
sectio n(Ypage 63).
ESP ®
monitors drivin gstability and traction,
i.e. power transmission between the tires and
the road surface.
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. The engin eoutput is also modified to
keep the vehicle on the desired course within
physical limits. ESP ®
assists the driver when
pulling away on wet or slippery roads. ESP ®
can also stabilize the vehicle during braking.
ETS (Electronic Traction System) i

Important safety notes PARKTRONIC is an electronic parking aid with
ultrasonic sensors. It monitors the area
around your vehicle using six sensors in the
front bumper and four sensors in the rear
bumper. PARKTRONIC indicates visually and
audibly the distance between your vehicle
and an object.
PARKTRONIC is only an aid. It is not a
replacement for your attention to your
immediate surroundings. You are always
responsible for safe maneuvering, parking
and exiting
aparking space. When
maneuvering, parking or pulling out of a
parking space, make sure that there are no
persons, animals or objects in the area in
which you are maneuvering.
! When parking, pay particular attention to
objects above or below the sensors, such
as flower pots or trailer drawbars.
PARKTRONIC does not detect such objects
when they are in the immediate vicinity of
the vehicle. You could damage the vehicle
or the objects.
The sensors may not detect snow and other
objects that absorb ultrasonic waves.
Ultrasonic sources such as an automatic
car wash, the compressed-air brakes on a 172

i USA only:
This device has been approved by the FCC
as a"Vehicular RadarS ystem". The radar
sensor is intended fo ruse in an automotive
radar system only. Removing, tampering
with, or altering the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.
Monitoring range of the sensors
In particular, the detection of obstacles can
be impaired if:
R dirt on the sensors or anything else
covering the sensors
R there is poor visibility, e.g. due to fog, heavy
rain or snow
R an arrow vehicle traveling in front,e .g. a
motorbike or bicycle
R the road has very wide lanes R
the road has narrow lanes
R you are not driving in the middle of the lane
R there are barriers or similarl ane borders
Vehicle sinthemonitorin grang eare then not
indicated. Blin
dSpotA ssist monitors the area up to
10 ft (3.0 m) behind your vehicle and directly
nex ttoy our vehicle, as shown in the diagram.
For this purpose, Blind Spot Assist uses radar
sensors in the rear bumper.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may
be indicated, especially if the vehicles are not
driving in the middle of their lane. This may
be the case if the vehicles are driving on the
inner side of their lane.
Due to the nature of the system:
R warnings may be issued in error when
driving close to crash barriers or similar
solid lane borders.
R warnings may be interrupted when driving
alongside particularly long vehicles, e.g.
trucks, for aprolonged time.
The two sensors for Blind Spot Assist are
integrated into the sides of the rear bumper.
Make sure that the bumper is free of dirt, ice
or slush in the vicinit yofthe sensors. For
example, the radar sensors must not be
covered by bicycle racks or overhanging
loads. Following asevere impact or in the Driving systems
